I got the same results when just removing the UPDATE folder and saving as an ISO and compressing the ISO without touching anything. I'm doing all this stuff with UMDGen 4.0.
As the nfo of the working version says.. you cannot rebuild the iso. Do not touch the update folder, just cso the iso as it is.
If anyone knows what they are actually doing its possible to hex edit the videos/update to just be null bytes, then make a cso and it should be like 350mb or so. You just CANNOT use umdgen or any repacking tool to do it, has to be manual.
